That's an odd looking fly for sure. The wing is especially confusing to me. It's too big, and for a caddis imitation I'd think you'd want it to tilt backward. But I guess I have seen mayfly imitations where the wing goes straight up. Never nearly that big though. I suspect that with the big wing and the antron shuck the fly won't sit the way you're thinking it will on the water. It's going to end up laying on its side, suspended by the tall wing and the antron/zelon tail. Maybe if you tie a heavy dropper off the bend it would sit with the tail and body in the water... I guess you'll have to fish it and see how it tends to ride in the water. But even if it does sit sideways, it may catch fish anyway! They're not really all that smart, after all.
